Associations exist between fine particulate matter (PM2.5) exposure and impaired kidney function. However, the specific mechanisms components causing renal damage remain unclear. PM2.5 was collected from an industrial a rural area. Mice were categorized according to exposure, biochemical, western blotting, histological, immunohistochemical analyses performed evaluate impact of constituents on their kidneys. To assess different inflammatory responses, study conducted by exposing murine...

Separation of metal from industrial sludges by hydrometallurgical process is usually complicated the presence polymeric coagulant added during wastewater treatment. In this study, a was proposed for recovery copper sludge printed wiring board industry. The first leached with citric acid solution to extract and zinc. leachate further purified using D2EHPA-modified Amberlite XAD-4 resin. During leaching process, more than 87% 79% Cu Zn, respectively, were dissolved solution. Dissolution...

This study investigates the atmospheric fine particulate matter (PM2.5) issue caused by multi-effect of complicated sources, terrain, and meteorology at Southern Taiwan. Three sampling stations represent an urban, a rural, coastal sites near urban-industrial complex. The PM2.5 were measured during pollution episode from November to February, when reference samples collected in April. sample was with constant-flow sampler Federal Reference Method performance. After determining mass, their...

Polychlorinated diphenyl ethers (PCDEs), persistent environmental pollutants, are found in flue gas from incinerators. While air pollution control systems (APCSs) capture the resulting sludge/fly ash (SFA) requires further treatment due to residual PCDEs and other harmful substances. This study investigated a hazardous waste thermal system (HAWTTS) utilizing flameless combustion technology alongside multistage APCS (scrubbers, cyclone demisters, bag houses). SFA was recirculated for...

POP data are limited in the marine environment; thus, this study aimed to investigate background persistent organic pollutant (POP) levels oceanic deep-water-deposited particulates South China Sea (SCS). Six POPs, including polychlorinated dibenzo-p-dioxins/dibenzofurans (PCDD/Fs), dioxin-like biphenyls (DL-PCBs), polybrominated diphenyl ethers (PBDEs), (PBDD/Fs), (PCDEs), and (PBBs), were investigated eight pooled samples from SCS 20 September 2013 23 March 2014 15 April 24 October at...

In this study, electrodes of titanium dioxide nanotube arrays (TNAs) were successfully synthesized by applying the anodic oxidation etching method, as well use green synthetic technology to add reducing agents tea or coffee reduce metal palladium from chloride. Synthesis modified TNAs (Pd/TNAs) was conducted microwave hydrothermal method after reduced. order identify surface structure, light absorption and elemental composition, Pd/TNAs characterized X-ray photoelectron spectroscopy (XPS),...

Re-suspension of iron ore dust presents a constant hazard in the working environment within steel production plants. Herein, optimal operating parameters for maximum suppression efficiencies through water mist generator and conventional sprinkler particulate matter (PM) originating from an pile measuring about 2 m height with stacking angle 30° are investigated. The effects including wind velocity, spray angle, mode supply on evaluated. Size differentiated PM samples were collected upwind...

The wall combustion is one of the soot and unburned hydrocarbon formation sources in engine cylinders, which affected by both spray parameters. impingement dynamics droplets on liquid films have been widely studied. However, there less focus droplet impingements hot film, more representative as a pre-wall condition. This work investigates ethanol heated glycerol film. Weber number (10 ≤ We 275) film temperature (70°C T 175°C) are two main parameters that lead to comprehensive understanding...

This study aimed to develop and validate a robust method for the simultaneous extraction of polybrominated diphenyl ethers (PBDEs), polycyclic aromatic hydrocarbons (PAHs), nitrated PAHs (N-PAHs), organophosphate esters (OPEs) bound atmospheric particulate matter. These compounds are widespread environmental pollutants with known detrimental effects on both human health environment. The concurrent microwave took total 40 minutes utilized n-hexane:acetone:dichloromethane (2:2:1 v/v). After...

Abstract This study examines the influence of lung geometry, physical activity intensity, and aerosol concentration on deposition efficiencies (DEs) particulate matter with surface-bound polycyclic aromatic hydrocarbons (PM- PAHs ) in human generations 3–6. Two-phase flows were effected ANSYS 2020R2 platform using planar orthogonal geometries, two levels activities, 4 Metabolic equivalents (METs), 8 METs. Aerosol concentrations 0.95 μg‧m -3 , 1.57 2.04 represent rural, urban, industrial...

The wall-attached fuel layer of the combustor usually leads to an unstable combustion and produces unexpected emission, such as aerosol particles unburn hydrocarbons. In this study, impaction ethanol droplet on a heated liquid surface was examined for investigating factors those could effectively control atomization avoided formation layer. We accelerated volatilization droplets after contacting even achieved flash evaporation condition burst oil layer, which conducive cleaning inner wall...

Pollution reduction related to combustion engines is considered be an important issue around the world. Hydrogen as additive energy has been utilized for alternative fuel since it need not require any modification. Particularly, a sustainable option diminishing petroleum dependence and air pollutant emissions. In this study, we investigated tailpipe emission with hydrogen addition different driving behavior such cold-start, idle, urban (UDC) extra-urban (EUDC) under New European Driving...

This study investigated the catalytic oxidation of isopropyl alcohol (IPA) over gravel covered by mixed metal oxides. Catalysts were prepared incipient impregnation with weight loadings and various mole ratios.
